Not really true, the hps will run more efficient and cooler compared. CFL's make a good amount of heat, and if ur planning on using something like 400wat hps then the cfls would add up, two 150wtt cfls about 20,0000 lumes will give off a decent amount of heat. In either case proper ventilation will be needed. If anything is more simple 1 400watter compared to a bunch of cfls i would pick the hps. Theres no reason to skimp out on lighting if u dont have to, a cheap 400w light that works good and $100 cooltube is far better. So ur light bill may be more, u may initially spend 100 extra bucks but it will be far more productive and efficient. In other words, u get more for the $$
